Data Propagation Delay Constraints in Multi-Rate Systems
Tobias Klaus, Florian Franzmann, Matthias Becker, Peter Ulbrich · 2018
Many industrial areas are faced with a continuous increase in system complexity, while systems need to satisfy stringent timing requirements, which are traditionally based on the tasks' local deadlines. However, correct functionality is subject to high-level timing requirements on data propagation through a set of semantically related tasks. Since distributed concurrent engineering is often used to deal with the complexity of such systems, violations of data propagation delay constraints are only visible at late development stages, where changes in system design become increasingly expensive.
